156 GINA V4.0 System Administrator Guide – September 2000

Overview

Figure 35 is a symbolic representation of the hierarchies in the deﬁnition of the system. It is

not drawn to scale to reﬂect the scope of the individual sub-descriptions.

Figure 35 The logical hierarchy when deﬁning the communication structure of a system

The communication structure of a system can be depicted by a graph with nodes and

edges. The nodes correspond to the applications, while the edges represent the communi-

cation channels. The blocks in the diagram deﬁne the nodes of the graph with respect to

the speciﬁc system, host or application. The edges of the graph represent the applications’

connections, with each application connected to all of the other applications.

From the input data (which has already been explained), the conﬁguration generator

config-tux creates the following output data:

– for each host

a GINA-speciﬁc address ﬁle containing all addressable server applications.

– for each application

a GINA-speciﬁc address ﬁle containing all addressable server applications and client

applications.

– for each transaction-monitored application

a GINA-speciﬁc environment ﬁle preset with the deﬁnition of the GINACONFIG environ-

ment variable.

etc.

Application-speciﬁc parameters

System-wide settings

Parameters valid throughout the system

Participating host: H1, H2, etc.

Host-speciﬁc parameters

etc.

Applications in R1, R2 etc.
